I see too many peaks in the spectrum for my compound - WKB544

Article number: 544

SYMPTOMS

  • Only one signal (m/z 1609.6) expected in the mass spectrum
  • Observe m/z 1609.6, 1610.6, and 1611.5 in the spectrum
  • Relative abundance of the m/z signals are 90, 100, and 60 percent, respectively

ENVIRONMENT

  • Xevo TQ-S
  • Mass spectrometry

CAUSE

Elemental isotopes and their relative abundance contribute to a distribution of signals from ionized compounds.

FIX or WORKAROUND

N/A (normal behavior)
